This paper describes an image compression method based on a hierarchical segmentation scheme into polygonal homogeneous regions. Adequate homogeneity criteria are selected through statistical discriminant analysis. Once segmentation is completed, the coding process consists in formingacompact representation of region shapes together with a suitable approximation of each region's content. Two types of coding are represented: a graphics-quality coding based on zero-order approximation of region content and a television-quality coding based on moment-preserving bi-level truncation.
